DEVICE FOR SHARPENING RAZO-RS.

SPECIFICATION forming part Of Letters Patent N 0. 455,165, dated June30, 1891.

Application filed m 18, 1890.

To aZZ whom it may concern.-

Be it known that I, PETER J. CAESAR, a

citizen of the United States, residing at Fergus Falls, in the county ofOtter Tail and State of Minnesota, haveinvented certain new and usefulImprovements in Devices for Sharpening Razors, of which the following isa specification.

This device relates to the class of razorsharpeners shown and describedin my applications numbered 288,899, 320,261, and 349,093, filed,respectively, October 23, 1888, August 9, 1889, and April 23, 1890, theessential difference being that the frame herein seeks to return therazor-holder to normal position by reason of its own weight, the framemoving in an arc of a circle, of which the pivot, which is paralleltherewith, constitutes the center on which it swings.

In order that my'invention may be fully understood, I will now proceedto describe the same with reference to the accompanying drawings, inwhich Figure I is a plan View of my device. Fig.

II is a side view, parts being shown in section. Fig. III is atransverse section on line III III, Figs. I and II.

Referring to the drawings, A represents the blade or razor holder, and Bthe frame, both of which are formed and arranged as described and shownin my last above-named application. At the inner end of the frame Bisformed an upwardly-extending projection or shoulder O, by means of whichthe frame is hung from a pin D, parallel with the frame and projectingfrom a vertical transverse support E, extending upwardly from the shaftor axis F, journaled in the handle G. The shaft is slightly bent, sothat the handle will not turn too freely on the shaft. The pivot II ofthe razor-holder passes through the base of the projection or shoulder Cand has fixed at its end the pinion I. Formed transversely in thesupport E is a curved slot .T, concentric with the pin D. This slotreceives the pinion I, which works therein and engages the teeth K atthe under side of said slot.

The friction-frame B for vibrating the device and causing the razor toturn being below its pivot, pressure on thehandle tends to assist thevibration; but the vertical support Serial No. 359,161- on model.)

E being above its shaft F the tendency is the reverse and pressure onthe handle tends to keep the support E vertical at all times. It willfurther be seen that the bearing-surface of the frame B is above theplane of the axis F, and therefore when the frame reaches the limit ofits vibration and the movement of the device as a wholeis continued forsharpening the blade the pressure on the handle still retains thesupport E in vertical position and the frame in proper position on thestrop.

. In this device no spring or other special means is required forreturning the razorholder to normal position, inasmuch as the frame issupported eccentrically-that is, from aboveand this causes it to returnby reason of its own gravity to central position and with it return therazor-holder.

The object in bending the shaft is to pre Vent the handle turning sofreely as that when the device is lifted off the strop the frame willswing around with the shaft as its axis.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

1. The combination of a suitable support,a swinging frame pivotedeccentrically upon said support, a reversible razor-holder mounted insaid frame, and means in connection with the razor-holder and supportfor reversing said holder, substantially as explained.

2. The combination of the handle, the support, and the razor-holder andreversing mechanism carried by the support, said support being pivotedeccentrically to the handle, substantially as and for the purposes setforth.

The combination of a reversible razorholder, a gravitating support,means in connection with said holder and support for antomaticallyreversing the holder, a bent shaft carried by said support, and a handlein which said shaft is journaled.

4. The combination of a handle, a shaft on I which it is fitted, asupport projecting upwardly from the shaft, a gravitating frame hungfrom said support, a razor-holder, and means for reversing the holderautomatically,

substantially as and for the purpose set forth.

5. In combination with ahandle andasupport, a frame having an upwardprojection or shoulder, a pivot-pin extending from the supportandpassing'through the project-ion above ing upward, a gravitating framehung from 10 and parallel to the frame, a reversible razorthe support,and a razor-holder carried by the holder carried by the frame and havinga frame, said frame and holder being all above pivot, a pinion on saidpivot, and teeth on the swivel of the vertical support, as and for 5said support concentric with said pin and enthe purpose set forth.

gaged by the pinion, substantially as and for PETER J. CAESAR. thepurpose set forth. \Vitnesses:
